Hi everyone, I'm attaching a SAS program that you can run for DROC #82. As mentioned on the call today, this program runs on the tumor table, and it returns entire records (with shifted date values) for all patients with 2+ records. It might be helpful to note that the resulting SAS file will NOT completely conform to the tumor table spec: the shifted dates will be in SAS date9. format with a "_S" appended to the date's variable name. Original, unshifted dates will be dropped. It's fine to run this program if your dates are already shifted, so long as the dates in your table are in YYYYMMDD character format. The only effect is that your dates will be shifted twice. (It is very important, though, that your applied shift is done identically across all records for a given patient.)
Please let me know if you have any questions... thanks! Brad ------------------------------------------------------------ Bradley D. McDowell, Ph.D. Director, Population Research Core Holden Comprehensive Cancer Center 5240 MERF | The University of Iowa | Iowa City, IA | 52242 Office: 319-384-1768
